Thinking about making an upgrade. Currently have a '00 9650 walker, level-land with 2700 sep. hrs. in good shape, through the shop every year. Looking at a '09 9770 with 1000 sep. hrs., pwd, great maintenance record, autosteer ready, 4x4 feederhouse. Both are corn & bean machines. It is quite a size jump. What would be a good boot price??? Thanks!
